MAX ROSNER, OF NEW YORK, N. Y., ASSIGNOR, BY DIRECT AND'MESNEASSIGNMENTS, TO EDWIN D. HENDERSON, JR., OF NEW YORK, N Y.

FIRE-ESCAPE.

To all whom it may concern Be it known that I, MAX RosNER, a citi- Zenof the United States, and aresident of New York, county and State of New,York, have invented a certain new and useful Improvement inFire-Escapes, of which the following is a full, clear, and eXactspecifica-' tion. I 1 This invention relates to a class of devicesadapted to be used for saving persons when in a burning structure. I I

My invention has for its object primarily to Provide a fire escape, ordevice designed to be employed upon a building,- or other structure topermit persons confined therein when endangered by fire to readilyescape without injury, and wherein is employed a chute adapted to becomposed of one or more integrally constructed sectionsso' as to providea continuous passage therethrough and which sections are disposed oninclines in opposite relative directions from each story of thebuilding, in order to avoid too precipitous a descent for persons-toslide down the chute especially when applied to high structures, p

Another object ofthe invention is to provide in the chute a number offreely rotatable members arranged adjacent; to each other transverselyof the chute and which serve to force the persons entering the chute tomove in a downwardly direction therethrough.- I I I A further object ofthe invention is to provide a fire escape which is susceptible of beingconstructed entirely of cement, or other material which isnon-inflammable and a non-conductor of heat, or maybe made of cement andmetal combined in a manner to prevent the flames of a burning structurefrom contacting with and heating the metal, and a still further objectof the invention is to provide a form of chute upon the top of which maybe constructed a stairway.

With these and other objects, in view, :the invention will behereinafter more particularly described with reference to theaccompanying' drawings, which form a part of this specification, andwill then be pointed out inthe claims at the end of the ,descrlption. sv I In the drawings, ,Figure 1 is fragmentary view of a building withone form of fire escape embodyingmy invention applied thereto, parts of{which are broken away. Fig. 2-is a view, partly in section, taken ,onthe lineI I-eIIof F ig l. Fig. :3

a number ofxthe rollers and rails used in con unct1on with the.fireescapeu Fig. 6 is an enlarged fragmentary view showing a s de elevation ofone of ithe. rails and end vlews of a number of the r'ollers. Fig. 7

is a fragmentary view, partly" in section, 7

taken on the line V V,of Fig. Fig. .8 1s a longitudinal section throughone of the rollers, and Fig. ,9 is an end .view of one of the rollers.

The fire escape, or devicehas chute 1O which is tubular in form, and ispreferably substantially square, or rectangular in cross section wherebytwo side walls ll and 112, a bottom .13, and a top wall Mareprovided.

When the fire escape is applied to a; building 5 as 14?, or otherstructure Of-II10I'6; th,a I1:OIl(- story in height the chute 10,is-constructed so as to be stationary therewith ,and is formed toprovide integral, sections, as. .15, 16, 17, with a continuous passagethere- .through, and each{ section .is ofalength to conformapproximately to" the height (of each story 'of the building. ,As;shownin the drawings, the sections 1 5, 16,17 are disposed upon inclinesin opposite .directions {relatively to each other to prevent too,precipitous: a descent for persons to .slide down the chute when thedevice is used in conjunction with achigh. structure. By providingreadily be constructed entirely ofv cement, or other material whichisfnon-inflammable and a non-conductor of heat, or may be constructedpartly of metal and coated: with the chute of thefshape mentioned iitmay cement, or th elilreso as :to be strictly fireproof as well astendinggto deflectthe heat from. a burning structure,. instead ofconducting the heat as is characteristic of fire escapes made of metal.

chute lOand adjacent to the'bottom thereof is a freely movablefloorwhichtserves as a slideway .18 composed of a number .of rotatablemembers, or rollers 18? which arear- Interiorly of'eacho-fthei-sectionsof the ranged adjacentito each other and disposed chute.

transversely of the sections of the chute. The rollers 18 may be of anysuitable material, but each is preferably made of a round bar ofmetalwhich is covered with cement, as 19, in a manner so that each endof the bar is free of coating to serve asshort shafts 20 and 20. Theshafts 20 and 20 of each of the rollers are rotatably disposed in spacedbearings provided in rails 21 and 22 one of which is arranged at eachside of the bottom 13 of each of the sections of the The sections 1 ofthe chute '10 are niadebf dimensions" whereby the person slidingtherethrough should be in a sitting posture, and'the rotation of therollers will then serve-to carry the person in a downward direction aswell as tending to prevent the person from stopping his descent bypressing the hands,ffor instance, against theside walls of thechute.When the chute is constructed of'a'number of sections, and

\ to check the rapidity of the descent of a person passing therethrough,I may dispense with the use of the rollers 18 at bends of the 'chutewhich form the junctures of the sections, "and instead flooring ofcement, or

the like maybe used.

The chute 10' has an entrance 23 at its upper end, and an exit 24 at thelower end thereof. Where the chute has a plurality of sections each'one'is of a length to extend from one story to the other of thebuilding,

and at each story may be constructed in conjunction'w'ith the chute aplatform, as 25, '26, 27, 27 Leading'into the sections 16 and17"from"the platforms 26.and 27 are entrances *28' an'd 29,respectively, to permit persons todepart from various floors of aburning building, and conveniently enter the chute" In order that thepersons entering the' sections of the chute at its various entranceswill be compelled to pass therethrough'in'the same direction, I providein the chutefat the'entrance of each of the sections except the topsection a branch slideway, as 30and'31, each of which is arranged toconverge with the main slideway of the chute, andithe floor of each ofsaid branch slideways may be free of rollers, or composed of rollerssimilar to' the rollers 18 Upon each sectionof'the chute may be provideda stairway,' as 32, if desired, which may also be used asa means ofescape from a building, and which is adapted to be constructed ofcement, or other like material.

' In the foregoing"description, I have embodied the'preferred form of myinvention,

but I do notwish to be understood as limiting myself thereto, as I' amaware that modifications may be made therein without departing from"theprinciple, or sacrificing any of the 'advantagesof this invention,therefore I reserve to myself the rightto make such changes as fairlyfall within the scope of theappended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent l. A device of the character described comprising afire escape for a building having a plurality of stories, said fireescape including in combination a platform for each story of saidbuilding, a rigid integral covered chute including straight portionsintermediate each platform, said portions being oppositely inclined oneto another, an entrance chute comprising a slide leading from eachplatform into said integral chute, turns in said integral chute beingformed adjacent to said entrance chutes, said entrance chutes beinginclined at a greater inclination than the inclination of said turns,the mouth of said entrance chutes and said turns being substantiallyside by side.

2. A fire escape for a building having a plurality of stories includinga platform for each story of said building, a rigid integral coveredchute provided with an open stairway on the upper side thereof, saidintegral chute including oppositely inclined portions and an entrancechute for each platform leading into said integral chute beneath therespective platform from which said entrance chute leads, substantiallyas described.
